DID YOU KNOW?
Twelve games in the 2013 Stanley Cup Playoffs have featured a game-tying or go-ahead goal in the final five minutes of regulation. Six game-tying goals have been scored in the final minute, including two by the Senators: Cory Conacher (19:37) in Game 4 of the Eastern Conference Quarterfinals and Daniel Alfredsson (19:31) in Game 3 of the Eastern Conference Semifinals. Ottawa won both of those games in overtime.

Before this year, the Senators had tied two playoff games in franchise history with goals in the final minute of regulation (scored by Dany Heatley in 2007 and Alfredsson in 2001). However, they lost both of those games in overtime. (Elias)

The last time an NHL team tied a postseason game with a shorthanded goal in the final minute of regulation was on April 24, 2010, when Chicago’s Patrick Kane scored at 19:46 of the third period to force overtime in Game 5 of the Western Conference Quarterfinals versus Nashville. The Blackhawks eventually won that game, 5 4, in overtime. (Elias)

MULTIPLE OVERTIMES
Sunday’s Ottawa-Pittsburgh game marked the first multi-overtime contest of the 2013 Stanley Cup Playoffs. The last postseason contest that required more than one overtime was on May 2, 2012, when the Rangers defeated the Capitals, 2 1, in triple-overtime of Game 3 of the Eastern Conference Semifinals.

The Senators have now played in eight multi-overtime games in franchise history. Their most recent was a 4 3 triple-overtime victory over the Penguins on April 22, 2010, in Game 5 of the Eastern Conference Quarterfinals. (Elias)

Pittsburgh has now played in seven multi-overtime games in franchise history. Its last was a 3 2 double-overtime win over Tampa Bay on April 20, 2011, in Game 4 of the Eastern Conference Quarterfinals. (Elias)

BECAUSE IT’S THE CUP
Ottawa forward Colin Greening, who recorded his first career playoff game-winning goal Sunday, played the final half of the game with pieces of fiberglass in his face after getting hit with a high stick in the second period. Greening needed five stitches to close the wound after the game. He has scored in each of Ottawa’s last three contests.

50 AND COUNTING
Ottawa captain Daniel Alfredsson scored his 50th career playoff goal, becoming the fourth player in NHL history to score 50 or more postseason goals for the team that drafted him without winning the Stanley Cup with that team. The others to do so are Brian Propp (52 goals for the Flyers), Denis Savard (61 for the Blackhawks) and Patrick Marleau (active, 57 for the Sharks). (Elias)

SOME TIMING
Ottawa forward Jason Spezza returned to the lineup Sunday for the first time since Jan. 27. Oddly enough, his return came 10 years to the day of his Stanley Cup Playoff debut. Spezza’s first NHL postseason appearance was in Game 5 of the 2003 Eastern Conference Final, when he recorded 1-1—2 to help the Senators defeat the Devils (although they would eventually lose the series in seven games). He was held off the scoresheet Sunday, but did register four shots on goal in 18:40 of playing time.

CLUTCH KRUG
Boston rookie Torey Krug gathered a pass between his legs to score his second goal in as many games. He is the first player to record his first two NHL goals in back-to-back playoff games since Detroit’s Justin Abdelkader in the 2009 Stanley Cup Final. Krug also is the first rookie defenseman to score goals in each of his first two postseason games since 1988, when Boston’s Glen Wesley tallied in his first three contests. (Elias)

TUUKKA TIME
Boston goaltender Tuukka Rask made 35 saves in Sunday’s victory. He has recorded 30 or more saves in five of his nine postseason starts, going 4-1 in those contests. Rask had 10 such performances in 36 regular-season appearances, compiling a 7-2-1 record.

BOY OH BOY
Johnny Boychuk’s goal at 12:08 of the second period proved to be the game-winner for Boston. Boychuk has nine goals in 54 career postseason games, including three in nine appearances this year. He has just 14 goals in 246 career regular-season games.

ROOKIES STEP UP
Rookie defensemen have contributed goals in each of Boston’s last three games. The trio of Matt Bartkowski (0-1—1), Dougie Hamilton (0-1—1) and Torey Krug (1-1—2) combined for four points Sunday.

2-0 TROUBLE
The Rangers face a 2-0 series deficit for the second time this postseason. They are 2-19 all-time when losing the first two games of a best-of-seven series, but one of those victories came in the opening round of this year’s playoffs, when they rallied to beat the Capitals in seven games. No team in NHL history has ever won back-to-back playoff series in which they trailed 2-0. (Elias)

RARE FIVE
NY Rangers goaltender Henrik Lundqvist yielded five goals in Sunday’s loss; he hadn’t allowed five goals in 151 consecutive games (regular season and playoffs) dating to a 5-2 loss at Anaheim on March 9, 2011. Lundqvist also had never yielded more than three goals in any of his 31 prior appearances versus Boston (regular season and playoffs). (Elias)
